PIN.

Specification of Letters Patent. Patented Feb, 28, 1922,,

"Application filed November 1, 1920. Serial No.421,076.

Tocll whom it may concern.

Be it known that I, lVAL'rnn E. JOHNSON, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Pins, oi? which the following is a description.

My invention relates to im n-ovcments in pins, and more specifically to that c ass of pins wherein it is desired to lock or guard the pin against accidental displacement. The principal object of my invention is to so construct a pin of this kind which shall be of simple form, durable, economical, easily manipulated, and withal, shall be extremely eflicient in use.

lVith the foregoing and other objects in view, my invention consists in the novel construction and arrangement of parts here in shown and described, it being understood that changes in the precise embodiment of the invention herein disclosed canbe made without departing from the spirit oi my invention as pointed out in the claim hereunto appended.

Referring to the drawings, in which like reference characters indicate like or similar parts throughout the views;

Fig. 1 is a plan view of the device;

Fig. 2 is a section on line 22 of Fig. 1;

Fig. 3 is a section on line 3-3-0f Fig. 1;

Fig. 4 is a sectionsimilar to Fig. 2 showing a modification of the device; and

Fig. 5 is a section on line 5-5 of Fig. 4:.

In the drawings, A designates a garment or other material to which the pin is secured, said pin being composed of two parts, namely, a piercing member 1 and a guard or supporting member 2, these parts cooperating as a unit to lock the piercing clement against accidental displacement from the garment.

The piercing member comprises a main portion 3, a pivotal portion 4, and a grip. portion 5, said pivotal portion being intermediate the grip and pin portions, whereby the pin may be gripped at 5 and pivoted about its guard 2. The pivot 4 is preferably in the form of an eye which is of a larger diameter than the main body portion of the guard, so that it may be easily slid thereon.

The guard is preferably of such shape that it forms a closed figure upon which the piercing member may slide and pivot, and of such size that its periphery will cooperate to piece split ring of resilient material, having its ends 6 suitably offset or enlarged at the split, thefree ends being normally in contact with each other and tending to close the split.

The piercing member is permanently positioned upon its guard, and in use the pin is gripped at 5 and reentrantly inserted through the material of the garment and the guard moved or slid under the pivot until its split is immediately above the pin, as shown in the dotted lines in Fig. 1. Then the split guard is swung beneath the pin and slid so that the split is past the pin, as shown in full lines in Fig. 1, the resiliency of the guard causing the split to close immediately after the pin is swung therethrough. In this positionthe guard overlies the pin and is fastened to the material of the garment so that the pin bears against the guard. The pin isthus securely held in place and is locked against accidental displacement, for the enlarged ends 6 of the guard will limit any accidental sliding movement between these two elements and prevent the pin from sliding past the enlarged ends. Nor can the pin lose its guard, for the enlarged ends of the guard are of a largerdiamcter than the eye of the piercing element and thus will prevent any detachment between the two elements.

Figs. 4 and 5 illustrate another embodiment of my invention, in which the ring or guard 2 is additionally provided with a recess or detent 7 thereon, spaced at any suitable point on its periphery, as for instance, about 90 degrees from the split ends, said recess being adapted to hold the pin therein against a sliding movement on the ring.

In order to remove the device from the garment, the guard must be rotated about its axis so that the split is immediately be neath the pin, then the pin is snapped through the split and the entire device is lifted ofl of the garment by the grip portion 5..

Having thus described my invention, it is obvious that various immaterial modifications may be made in the same without departing from the spirit of my invention; hence I do not wish to be understood as limiting myself to the exact form, arrangement, construction and combination of parts hereinshown and described, or uses mentioned, except as defined by the claim hereunto appended.

What I claim as new and desire to secure by Letters Patent is:

In a device of the kind described and in combination, a piercing pin member adapted to be inserted through the material with said opening, the opposed ends of said ring being normally in abutment with each other, and said piercing member being bodily slidable on the ring, so as to be moved entirely through and past said split out of radial alignment therewith and to engage in said notch and overlie said guard ring.

In testimony whereof, I have hereunto signed my name in the presence of two subscribing witnesses.

\VALTER EDGAR JOHNSON.
